Series consists of bound notebooks and looseleaf writings. Some notebooks are handwritten; most have been transcribed. Soper illustrated some of the notebooks with colour pencil sketches and occaissionally pasted in a photograph. The original reports are in chronological order. They are organized as a manuscript draft and were written for the National Museum, Canadian Wildlife Service or the University of Alberta Department of Zoology. Serveral groups of reports are bound in single hard cover and were destined for a discrete office. The sketches, narratives and other manuscripts are less organized and lack a cover page, index, or at times, pagination.
The series title is based on the contents of the records.
